Christina wanted to know more about the effects of earthquakes, so she created a model and performed an experiment. in christina's model, she carefully layered different types of rock and soil in a large, clear, plastic container. after taking a picture of the layers through the side of the container, she shook the container from side to side. then, she compared the layers in the container with the picture taken before shaking and made note of the differences. what is a benefit of christina's model?

What does a complete balanced chemical equation include? a. exothermic coefficients b. endothermic coefficients c. valence electrons d. molar coefficients

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
